Handle three possible outcomes.
TypeScript: Check high, normal and low values with an ordered conditional chain.
const temperature: number = 20;
console.log(temperature > 30 ? "Hot" : temperature < 10 ? "Cold" : "Normal");Expected output EXAMPLE
Normal
Details
Requires TypeScript and Node.js. Save as snippet.ts, compile with tsc --strict --target ES2022 --module commonjs snippet.ts, then run node snippet.js.

Test inputs, results and environment
The exact published code ran in a dedicated Linux test container with prepared inputs. Snippet process uid 65534 with a read-only root filesystem and temporary working files. Networking disabled. Fixtures and output records are isolated from the application database. Testing covers this example and its stated checks, not every input, operating system, or runtime version. The Linux container shares its host's kernel; this is not a native Windows test.
